HPSD CHARACTERISTICS
• The required steering torque when turning the handlebar fully (within angle B) is greater than the required steering torque when turning the handlebar slightly (within angle A).

• When the steering is in the neutral position, HPSD generates no damping force and has no effect on steering torque.
• The steering torque differs between the extension and compression of the damper rod.
• The required damping force is controlled when the damper piston travels across the groove in the damper case.
• The required steering torque differs between high and low damper rod speed.
|
extension across the groove
|
Turning the handlebar from neutral position to full angle (extension).
When the damper rod is extended outside of the groove:
Damping force is generated when the oil flows through the valves and adjuster piece in the damper case.
|
|
When the damper rod is extended across the groove:
Damping force is controlled when the oil flows through the groove in the damper case.
